The actuator controls the vane angle depending on the supply air temperature

Wax-bulb actuator

In applications where both heating and cooling are provided, the air pattern can be changed automatically via a wax-bulb actuator. The wax-bulb actuator alters the angles of the horizontal rear vane depending on the supply air temperature. Neither auxiliary energy nor a dedicated control system are needed.

When cold air is supplied at a temperature up to 18°C the supply jet is horizontal. The vane angle is 0°. As the supply air temperature rises, the actuator piston progressively changes the angle of the rear vanes in order to direct the supply air jet downwards. The vane angle reaches 45° in 10 to 20 minutes. No maintenance is required for the wax-bulb actuator.

Supply air is supplied into the space with either horizontal and/or vertical deflection. The supply air mixes with room air in front of the grille. The supply air is directed horizontally with the adjustable rear vanes. The length and form of the flow pattern can be adjusted by turning the vertical vanes.

The rear vane angle can also be controlled by an optional wax-bulb actuator.

The grille is connected directly to the duct. For the size of the installation hole, see Dimensions page (LxH). The grille is fastened to the duct with visible screws in pre-drilled holes in the frame.
